Making an international call to Denmark might seem easy, but the varying format, prefixes, and country codes can confuse anyone.

We have covered everything in this blog. We aim to provide a comprehensive analysis of Denish phone numbers, including details on format, geographical codes, time zone implications, Business format, and newly updated rules and regulations.

What is the Denmark Phone Number Format?

Denmark has a really good and modern phone and internet system. The Danish Energy Agency, called Energistyrelsen, makes sure everything works well and follows the rules set by the European Telecommunications Standards Institute (ETSI). They help keep the service reliable and up-to-date for everyone.

Denmark follows a simple phone number format, using the country code +45. The phone numbers are 8 digits long, with the first one or two digits indicating the service type or region. There are no traditional area codes, and the prefix helps identify whether the number is mobile or landline.

Country Code: To call Denmark internationally, you would have to use the country code +45.

Area Code: Denmark has no traditional area codes. The first digit(s) of the 8-digit number are not standalone area codes but instead indicate the service type (mobile, landline, etc.) or region.

Prefix: The prefix is the first one or two digits of the 8-digit number and indicates the type of service, mobile or landline.

Line Number: The 8-digit number is broken down into two parts; the line number is the remainder of the eight-digit number, completing the full phone number.

Example:

Mobile Number: +45 30 12 34 56 (mobile number with “30” as the mobile number prefix)

Landline Number: +45 32 12 34 56 (where “32” is a possible landline number from Copenhagen).

Types of Denmark Phone Number Format

1. Landline Number

Denmark’s landline phone numbers have 8 digits, and they don’t use area codes for cities or regions. For local calls, you don’t need to use the country code. Just dial the 8-digit number, like 32102030.

If you’re calling Denmark from another country, you need to add the country code, +45, before the 8-digit number, like this: +4532102030. Denmark doesn’t use area codes, so the first digits of the number might show if it’s a mobile or landline, but they won’t tell you the location.

With this streamlined system, it shouldn’t matter whether you’re calling within Denmark or from abroad – the structure of the phone number remains easy to understand.

2. Mobile Number

As the mobile numbers are not tied to any specific geographic region, users can move around within the country and Denmark and keep the same number.

Mobile numbers like these, which are mostly used for both personal and business communication, have their unique prefixes like 20, 30, 40, and 50. The eight digits of all Danish mobile numbers are standardized for mobile communication throughout the country.

A Danish mobile number would be dialed in its full eight-digit form for local calls, like 30123456. From abroad, the country code +45 is added to the eight-digit number, making it an international format, e.g., +4530123456. This simple system makes it easy to recognize and dial Danish mobile numbers, locally or internationally.

3. Toll-Free Number

Businesses and services in Denmark have toll-free lines set up so that clients may reach them for free. Since these numerals typically begin with the prefix 80, they are simple to recognize.

Important Features of Danish Toll-Free Numbers:

Format: +45 80 XX XX XX

Denmark country code: +45

Toll-free number prefix: 80

The remaining last six digits complete the eight-digit number.

Local Phone Calls: To access a toll-free line in Denmark, just call the eight-digit number (for example, 80 12 34 56).

International Calls: The international access code, +45, and the eight-digit number (for example, +45 80 12 34 56) must be entered when calling a Danish toll-free number from outside the nation.

4. Emergency Number

The emergency number in Denmark is 112 and you use it to call police, firefighters, or an ambulance. This number offers immediate help in an emergency and can be called without any charge from any phone in Denmark.

112: For emergencies involving police, fire, and medical services.

114: For non-emergency police assistance.

1813: For non-life-threatening medical assistance outside of normal doctor hours.

118: For directory assistance to find phone numbers

Denmark’s Phone Number Regulations and Updates for 2025

By the year 2025, Denmark’s phone number system will continue to use a standard eight-digit format without area codes, thereby making it easier to use for all landline, mobile, and special service numbers.

Consumer freedom is increased thanks to mobile number portability, which keeps consumers’ numbers when they transfer providers. New prefixes for mobile and special services have been allocated in response to the increasing demand for numbers, avoiding shortages.

Furthermore, companies can now build a local presence without a physical site due to the increase in the number of VoIP. With the goal of preserving quality and protecting consumers, the Danish Energy Agency regulates telecommunications services to ensure compliance with national and European Union standards.
